Does anyone know of a company that can remove a non-reworkable underfilled BGA?

I see that Air-Vac sells a high precision milling machine that can claims to be able to do this.

We have 20 boards with a 0.79 mm x 0.79 mm BGA that needs to be removed.  The closest component to this BGA is about 0.4 mm away.

Thanks
Peter
